This Vapplication is a 'co'ntinuationin part of my copending application 4Serial'No. 701,969 led December 12, 1933, which is a division of Patent No. 1,938,907. v

In Fig. 1 each of the keys -i Vto 9 inclusive, of the various columns making up the keyboard is held in its normal position by a compresison spring 21 acting between plate H and a seat 28. Actuator bars I3, of which there is one for each column of keys, are provided adjacent their top and 25 bottom edges with laterally projecting stops Il, I5, I6 and I1 adapted to cooperate with a proiecting portion 35 or 36 (Fig.'2) of a certain key of the column with which the bar is associated so that when the`ke`y is depressed and the bar is moved, the stop engages the projectingportion of the key to limit the operation of a printing segment 8l by the actuator bar to a number of increments of movement corresponding to the value of the depressed key. The arrangement of the projecting portions on the various keyV stems and their relation to the stops on the actuator bar is'more fully Vdescribed in my prior Patent No.- 1,823,859.

At one side of each column of key stems isfa key stem lock 29 journalled in the plates 30 and 3|, so that it can swing into and out of engagement with laterally positioned depressions or notches 2Gb and 29e formed in the key stems adjacent their upper ends.

Near the forward end of each: actuator bar I3 is a slot ll for receiving a bar lock for the actuator bar and a slot I9 iorrreceiving a zero lock for the actuator bar as shown'in Fig. 5./ Referring to Fig. '3, the bar locks consist of a series of members Il, 42, 43, one for each actuator bar, pivotally mounted on one side of the plate Il at M, 45, '46, 41. When no keys are depressed the bar'locks depend perpendicularly, as indicated by the position at 40, with solid portions of their lower ends in the slots 38 of the actuator bars and consequently all the actuator bars are locked against movement. Each bar lock is provided at its lower end with a slot 48, 49, 58, 5|.

5 Laterally projecting members such as, pins 52, 53, 54, 55, are carried by the bar locks and are engageable by arms 56, 51, 58, 59secured to the key-stem lock trunnions 29a, which extend through plate 30, to move the bar locks so that their slots register with actuator 'bars for the related columnfto permit their movement.

A single spring 6I) associated with the righthand bar lock 43 biases all the bar locks into locking relation with the slots 38 of the actuator bars.

The zero locks for the actuator bars comprise members 64, 65, 66, 61 (Fig. 4), pivoted on the other side of the plate 30 at 68, 89, 10, 1I. The 4zero locks are biased by individual springs 12 so that their lower ends rest in the slots 39 of the respective actuator bars. The slots 39 in each actuator bar is wider, as shown in Fig. 5, than the zero lock by an amount equal to the distance the actuator bar must travel to bring the printing segment 84, to be presently described, into position to print a zero.

The zero locks normally prevent the actuator bars I3 moving more than enough to bring the printing segments to zero position. Adjacent their lower ends the zero locks are provided with projections such as pins 8|), 8|, 82, 83, adapted to be acted upon by arms 16, 11, 18, 19, carried by the key-stem locks 29 of the respective columns so that when a. key is depressed in a column the zero lock for the corresponding actuator bar I3 is moved out of the slot 39 in the bar permitting the bar to be moved toindex the printing segment 84 in accordance with the .value of the depressed key.

40 The bar locks and Zero locks, when released, are held out of locking relation position by the arms 58, etc., or 15, etc., carried by the key-stem locks acting against the pins'52, etc., or 80, etc. This is because when a key is depressed the keystem lock 29 is moved out of the notch 29h in the key stem a'nd engages the notch 29e which is of lesser depth so that the key-stem lock does not return to its normal position until released from locking relation with the key stem.

Referring to Figs. 2 and 1, a bar 29d having a slot 29e for each 'key-stem lock 29 is provided for releasing the -key-stem locks from the key stems, so that the-depressed keys may be restored by their springs 21, and for moving the arms 56,

etc. and 16,' etc., associated withthe pins on the bar locks and zero locks,l respectively, to permit locks which have been released to be restored to locking position by the springs associated therewith, as described in my copending application Serial No. 701,970. The bar 29d is biased to normal position by a spring 29f so that the notches 29e are normally 'disposed to permit movement of any key-stem lock on vdepression of a key in the corresponding column.

Below actuator bars I3 and the main shaft I5I which has an operating handle, not shown, is the restoring -frame shaft |03 (Figs. 1, 11 and 12). vThe restoring frame shaft has adjacent each end thereof an arm |5|b connected by link |5Ic and arm |5|d to shaft |5|. Shaft |03 is operable in one direction by main shaft |5| vand in the opposite direction by springs |5|e connected to pins I5|f on arms I5|b and to the frame `of the machine at |5Ig. Mounted on the shaft |03 are the restoring frames |04, one for each actuator bar,

having at their upper ends studs |05 which control the actuator bars I3. A The actuator bars have lugs |3d projecting through elongated slots in the plate I2 and connected to one end of springs I3c for moving the 5 actuator bars rearwardly, the other ends of the springs being connected to the plate at I3b. At their rearward ends the actuator bars I3 have racks 3 1 engaging toothed portions 85 of the printing segments 84, preferably mounted on a 10 common shaft 84a with proper provision for retaining them in alignment with the actuator bars. The printing segments 84 are illustrated as having printing portions 86 on their edges, the printing portions 86, as shown, being provided with 15 eleven divisions, one blank and the other comprising type from 0 to 9. A platen 88 and a ribbon 81 act in conjunction with the type on the segments 84 to effect printing. l

The platen88 has a shaft 89 supported ad- 20 jacent each end by frames 88a pivoted at 88h and connectedv by links 88e to arms 88d carried by the main shaft |5I. In order that the platen and ribbon may be moved against and away from the type faces .at the proper times the links 88e have 25' a pin and slot connection to frames `88a,*so that the frames are moved by the main shaft at the end of the forward stroke of the operating handle. Springs 88f are provided to move the platen 88 away from segments 84. Shoulders 881` formed 30 on slots 88e in links 88e are adapted to engage studs 88h to move the platen frames 88a to effect printing. The links 88e have cams 88s engaging a bail 88t for raising the links 88e so that the platen 88 may be moved away from type faces 86 35 by springs 881 after printingyhas taken place, the studs 88h moving in the extensions 88u of the slots.

A bell crank 6I, Fig. 3, is pivoted on plate 30, engages the bar lock 40 at the extreme left and o is connected by a link 6Ia to one end of a lever SIb, Figs. 1 and 6, pivotally mounted on plate I2. The other end of lever 6| b extends adjacent restoring frame shaft |03 which is provided with a cam or stud |830 (Figures l and 6). Stud |030 is positioned for engaging and locking lever 6|b to cause release of all bar locks after printing has taken place, to permit the previously locked actuator bars to be moved one increment rearwardly by springs |3c. This increment of rearw ward movement is provided to insure that all bars are positioned lfor effecting such transfer operations as may be necessary andlalso to permit totalizer engagement with driving segments 84,

as subsequently described. l u

Numeral wheel pinions 90, each associated with a cam 9| so -that a pinion and cam move together, are mounted on a shaft 94, (Figures 1, 10 and 13) which is supported by a frame 92 adjacent each end. 'I'he frames 92 are pivoted on a w shaft 93 and springs 92a, connected between the shafts 84a and 94, are provided to bias the pinions 90 into engagements with the toothed portions of the segments 84. Forward of each numeral wheel pinion is a pinion lock 95 having teeth a adapted to mesh with the pinion 90 to retain the latter in its operated position.

A latch 92h pivoted at 92e is provided for each frame 92 and is biased into engagement therewith by a spring 92d for normally holding the 70 numeral pinions 9 0 out of engagement with the toothed portions 85.- The ystuds |05 of two of the restoring frames |04, those adjacent the pinion frame 92, extend laterally from their frames |04 and are adapted. .to engage and release the 15 aioaocc latches 92h on rotationvof the arm |84 in a counterclockwise direction as the actuating hanpasses from 9 to 0 position, the/raised portion 9Ia of the cam causes the lower end Illc of the lever to be moved out of the path of movement of a stop |02 adjacent the rack 81 on the actuator bar I3 associated with the numeral pinion of the next higher order. For example, the transfer mechanism illustrated in my copending application Serial No. 81,198 may be employed, and is illustrated herein. The frame 92 is retractedvafterA an additive transfer by means of the bar |88 slidably mounted on the frame of the calculat- Ving device and normally urged toward the frame 92 by spring |39. The bar '|88 is moved to'the right against the tension of the spring by the lever I4I pivotally mounted at I4|arand carrying at its lower end aA pivoted latch I4Ie nor- Imally urged clockwise by a spring I4If but nor- .mally maintained in alignment with the. lever I4I gar teeth as. Prior to tripping .of latch nb the l actuator bars I3 have set the printing segments 84 to positions corresponding -to the keys depressed.

y Rearward movement of the actuating handle rotates shaft ISI counteiclockwise, shaft |88 clockwise and levers |84 and pins |89 move bars Il` forward rotating printing sectors 84 and accumulator gears 98 to produce an additive reading on the accumulator. Atthe end oi' the return movement of the actuator handle cam |88 trips latch |48, rele the bar |88 which is4 driven to the left against frame 92 by spring |89 to disengagegears 9| and relatch frame 92 with latch 92h.

A subtraction 'step'is similarly produced with the exception that the frame 92 is released by tripping latch 92h prior to rearward movement of bars I8, so that the gears 98 mesh with gears m85 during rearward movement of barsfIB and "extends transversely of' the machine and has are unmeshed at the end of the rearward movement. This action is produced by thefollowing mechanism'.

The movement of the bars |88 and the associated mechanisms is best shown in Figs. 11 and 12. With the elements of the device in the position shown in Fig. 11, the device is in condition for transfer operation. Pig. 12 illustrates the Y relative pomtions of the parts of the device at the time the frames are released to mesh the accumulator gears with the segmental gears.

A subtracting lever 8b projecting through the casingissecuredtoshaftmandisconnected to a link 98d (Figures 1 and 10). The shaft 98e fixed thereto adjacent its other end an arm 98j connected-to a link 88a, Fig. 5. As shown .in

'ing cycle.

Figuress and 1o tneiink ssd has a slot ne.

which receives a stud 98h on an. extension 98t of the, lever 98. The lever 98 is pivotally mounted on .a shaft 98s extending across the frame of the device. The link 98g is similarly connectedto a lever .98 adjacent the other frame 92.

Springs 98a bias the-levers 98 to the position shown'in Figs. l and 9. The levers 98 support bails Illld and I8`Ie, the bail ||I|d acting on upward movement of levers 98 -to move .the end I8Ib of each adding transfer lever III from contact with the cams 9|. The transfer levers I8I are retained Iin displaced position by friction or by any othersuitable means. The frames 92 rock rearwardly and forwardly, as indicated previously, during adding and subtracting operations carrying the transfer levers IBI with them. The bail IIIIe is normally positioned toengage the ends IIlIc of transfer levers IM in their forward position and restore the latter to engagement with the cams 8| at the end of an operat- Spring's -98i bias vthelever 98D and the parts connected thereto to normal position.

In order that pinions 98 may be meshed with the toothed portions 85 o i the printing segments 84 at the proper time foreffecting subtraction, the lever 98h is operatively connected to slides I82, one of which ismounted on each of the frames 92 and suitably guided at 62a for vertical movement as shown in Figures 9 and 10. The links 98d and 98g' operable by shaft 98e are connected to bell cranks 98p, each pivotally mounted I actuating links. 98d and 98g, and the connections 82d, 82e permit movement of the slides without movingV the links, whereas the rocking of bell cranks 98p by subtracting lever 98h through the links acts through studs 82d to raise the slides. I Adjacent its lower end each slide carries a stud 92h, Figures .1 and 10,adapted to engage the arm 63a of a bell crank pivoted on the frame of the machine at 83h. I arm 88e of each bell `crank pivotally supports a latch tripping member 92j adapted on rocking of the bell crank to engage a pin 92g on the pinion frame latch 92h. to move the latter about its pivot out of latching relation with the associated pinion frame 92. A spring 63d is connected to trip 92j and pivot 63h for vrestoring trip 92! and bell crank 63a.

Referring again to Figures 9 and 10, slide 82 hasa. cutout 'portion 82e which normallyiegislters with a cutout' portion 921' on the adjacent frame 92. When the pinions are in engagement wth the toothed portions 84 of sectors 85, the slots 82e, 921, normally permitv the free movement of studs 88g carried by the links 88o connecting the platen fr ames 88a to the main shaft ISI. When the slides 82 are raised the cutout portions 82e move from 'registration with the cutout portions 92 of frames 92 and solid vportions of theslides align with the cutout por- 'Ihe other erably stronger than springs 92a and actfwhen extended by contact of studs 88g with slides 62 to move frames 92 to disengage pinions 90 from the toothed portions at the end of the printing operation and to maintain the pinions demeshed until latches 92h become effective to hold the frames against movement in subtracting and totalling operations; as will be described.-

A total key 14 and subtotal key 15 are guided inthe plates III and I|. A key-stem lock 14a, Fig. 4, similar to locks 29'for the numerical keys is provided for engaging notches in the keys 14 and 15 to maintain the latter in depressed position until the lock is released, whereupon the keys may be raised by their springs. Keystem lock 14a is operatively connected by link 14C, 14e with locks 29 for the numeral keys so that it is released therewith. A shaft 14h extends transversely of the machine and adjacent one end has an arm 141 (Fig. 5), and adjacent the other end a bell crank 14k. One arm of bell crank 14k is connected to total key 14 so that depression of the latter rocks the shaft 14h. The other arm of the bell crank and the arm 14i are connected by links 141 and 14n to levers 14p which are pivotally mounted on the slides 62. The links 141 and 14n have pin and slot connections 141- to the levers 14p, and .are restrained to substantially linear movement so that movement of links 142 and 14n by depression of key 14 causes slides 62 to be raised.

The total key has a lug. 14g positionedabove a lug 15o on the subtotal key (Figure 1), so that depression of the total key also effects depression of the subtotal key. The subtotal key is connected to one arm of a bell crank 15d fixed to a shaft 15e. As shown in Figure 10, the other arm of bell crank 15d is connected by a link 15f to an arm I29b on shaft 29 on which cipher locks |34 are pivotally mounted. Cipher locks |34 arecontrolled by levers |24, operable by pinions eams 9|, and by latches |35 to prevent cipher printing to the left of a significant iigure in totalling operations as described in my Patent 1,938,907. The shaft 15e extends transversely of 'the machine and adjacent its other end carries an arm 15g'(Figures 5`and 13) connected by a link 15h to another arm v|291) also mounted on the shaft |29. 'I'he shaft |29 is mounted for vertical movement in guides on the main frame of the device. 'I'he arrangement is such that depression of the subtotal key, or depression of the total key acting through the lugs 14g and 15e on the total and subtotal keys, causes a toggle movement of the links 15f and 15h rearwardly moving shaft |29 yupwardly in its guides, and this upward movement causes the ends of the cipher locks |34 to move into position to be engaged by shoulders |33 on the actuator bars.

The links 15J and 15h are connected to bell cranks 15k, one of vwhich is pivotally mounted adjacent each frame 92. The bell cranks 15k are also connected to members 15l each havingto cause movement of the ends IDIc of transferY levers IOI suiciently to disengage them from the stops |02 on actuator bars I3 and thereby permit movement of frames 92 to cause-engagement of vpinions with. the toothed parts of segments 84. However, this movement of transfer levers IUI is not great enough to move the ends IIlIb of the levers from the paths of the raised portions 9Ib of cams 9| and thus the transfer levers remain effective to serve aszero stops for the pinions 90. 'I'he links '15j and 15h are also provided with studs 151' for engaging the arms 63a of the bell cranks to cause release of the frame latches 92h.

The lug 15o on subtotal key 15 is adapted to engage and operate a bell crank 13a associated with the zero locks 64, etc. (Fig. 4). A suitably guided bar 13, operable by bell crank 13a, and having slotsy 13b, into which the pins 80, etc., carried by the zero locks extend, is provided for simultaneously releasing all the zero locks. Key 15 also has a lug 15a for operating bell crank 6I which pertains to the bar locks 40, etc. (Fig. 3). Thus, operation of subtotal key 15, directly or from total key 14, effects simultaneous release of the bar locks and zero locks for all the actuator bars.

Other elements which would be embodied in a complete machine to operate in conjunction with the subtracting 'lever 98h, and total and subtotal keys 14, 15 for registering and listing functions are disclosed in my PatentNo. 1,938,907 but are omitted herein to simplify the .present disclosure. v

-The operation is as follows:

When a key in any column is depressed the key-stem lock, 29 for that column is moved out of engagement with the notch 29h of the key stem. The arm 51, for example, moves with its key-stem lock and acts 'on pin 53 of the bar lock 4| moving the slot 49 into alignment with the actuator bar I3 to permit its movement. This is illustrated in Fig. 3, 'Where depression of a key in the fth column from the right has caused the key-stem lock 29 of that column to move arm 51 releasing bar lock 4I for actuator bar I3 of the fifth column. The bar lock 4I has caused the release of the bar locks for the actuator bars of all columns to the right. It should be noted that the bar Vlocks 40 for the columns to the left of the vfifth column remain in locking position. It should also be noted that unless a key is depressed in a particular column the related keystem lock 29 is not released, the pin 54, 55 on thebar lock moving therewith away from the arm 58, 59, carried by the key-stem lock. 'I'his is illustrated in the first, third and fourth columns, while the position of the arm 59a indicates that a key has been depressed in the second column also. l

The arm 11 also moves with the key-stem lock 29 for the iifth column and acts on the pin 8| on the zero lock 65 for that `column moving zero lock 65 out of the notch 39 in the actuator bar I3. As the keyis depressed, the key stem portion between notches 29h and 29e acts on keystem locks 29 to cause the bar locks and zero locks to be moved slightly beyond released position by arms 51, 59a and 11, 18. Springs 60 and 12 act on the right bar lock and the released zero locks to move arms 51, 59a and 11, 18, through studs' sa, 55a, etc. and si, s2 to move the keystem locks sufliciently to eng/age notches 29e to hold the keys in depressed position.

When the operating handle secured to the main shaft I5I is moved forwardly, the restoring frame shaft |03 is moved counterclockwise carrying the restoring frames |04 and permitting springs I3c to move the actuator bars rearwardly (Figuresl, 11 and 12). The actuator bars for by racks 31 to an' amount `corresponding to the value of the depressed keys.

The combination of the bar locks and the zero locks insures the printing of zeros to the right of any key which is depressed and inhibits the movement of any actuator bars to the left of that key. This is for the reason that any bar lock which is thrown out carries all of its right hand neighbors with it to permit the actuator bars for these columns to move' at least enough to index the printing segments in zero printing position while the zero locks normally release individually and only on depression of keys in the corresponding columns. The actuator bars for columns to the right of a column in which a key has been depressed move rearwardly a lsingle Vstep to move the printing segments 84 for these columns to zero printing position, the

movement of Vthese bars being limited by their zero locks. Bars I3 for columns in which keys have been depressed have their zero locks released and move rearwardly a .number of increments corresponding to one more than the value of the key depressed. 'I'he actuator bars to the left of the amount entered on the keys are held lby their bar locks and do not follow the movement of the restoring frames 4| 04.

As the restoring frame shaft is rotatedv the cams |38 turn therewith and pin |5|h rocks the lever |4| retracting bars |38 from pinion frames 92 to permit numeral pinions 90 to be moved bysprings 92a from 'engagement with pinion locks 95 and into engagement. with the toothed portions 85 of printing segments 84, as will be later described. However, pinions do not engage the toothed portions 85 during the rearrward movement of the actuator bars in addition, inasmuch as the pinion frames are still held by the latches' 92h.

After the segments 84 have been indexed in printing position the studs |05 of restoring frames |04 move rearwardly therewith away from the actuator bars |3 which are held by the key-stem stops, bar locks, or zero locks, as the case may be.

The platen frames 88a are brought forwardly by the main shaft |5| through the arms 88d and links 88e and subsequently to the termination of the rearwardfmovement of the actuator bars the platen 88 and the ribbon 81 engage the type portions 88 of the segments 84 which have been adjusted to the printing line in accordance with the movement of the actuator bars. After links 88o have moved the platen against the type faces the forwardmovement of the links 88e causes the cams 88s to engage the bail 88t bringing. the slots 88u into register with the studs 88h on the platen frames; Springs 88! then act on the platen frames to move the platen away from the type faces es studs 88h move in the -parts 88u f the slots 88e.

Afte printing has been effected the stud |03`c moving with restoring frame shaft |03 strikes the inner end of and moves lever 8|b clockwise as viewed inFig. 6 about the pivot and acting lall the/non-released bar locks 40 about their pivots to released Aposition with the slots at lower ends ofthe locks in alignment with the actuator bars I3. The previously locked actuator bars,

those to the left of the fifth column under the conditions assumed above, are then'moved rear- N wardly by their springs |3c a single increment, the movement of the bars beinglimited by the engagement of the rearward end of slots 39 with the zero locks.

At the end of the forward stroke of the operating handle the studs |05 on the restoring frames adjacent pinion frames 92 contact the latches 92h as shown in Figure 12, disengaging the latter from the pinion frames, which are then moved rearwardly bythe springs 92a so that the pinions 90 move from engagement with the pinion* locks 95 .and,/into engagement with .the toothed portions 85 of the printing segments.

When the operating handle is released the main springs lila', which were tensioned during the rearward movement of the'restoring frames IM, turn restoring frame shaft |03 carrying frames |04 therewith, to engage the actuator bars for moving them forwardly. The studs |05 on the restoring frames adjacent the pinion frames 92 move from engagement with the latches 92h and the springs 92d move `theselatches into position for subsequently locking the pinion frames.

When st uds |05 reengage the actuator bars the latter are moved forwardly and the racks 31 thereon restore the printing segments 84 and the zoA toothed portions 85 thereofQbeing engaged with the pinions 90, operate the pinions in accordance with the numerals entered on the keyboard. As the actuator bars move forwardly the stops |02 engage the ends ',|0|c of transfer levers |0| which hold the actuator bars 'one step from'normal position.

During return movement of the actuator handle, the lever |4| rotates clockwise from the poof the stop |02 on the bar I3 of next higherorder, in preparation for the transfer operation which is performed in the manner described.-

At the end of the rearward mvement'of the.

operating handle the cams |36 on shaft |03 effect the release of the bars |38 for engagement with pinion frames 92. The impact of the bars |38 rocks the pinion frames 92 to move pinions 90 from engagement with the toothed portions 85 and into engagement withthe pinion locks 95. As the pinion frames 92 are moved rearwardly the transfer levers |0| are carried therewith and the ends Illlc of the transfer levers |0| which have been tripped to eiect'a transfer'` engage the ball lille. carried by the levers 98 and are restored to normal position. 'y

As the pinions 90 are demeshed the frames 92 move latches 92h downwardly and studs 92h. move with frames 92 to permit the springs 63d` to position trip members 92f above the pins 92g on the latches (Fig. 1). Latches 82h, biased by springs 92d, engage frames 92 and' lock the pinions 90 in their non-meshing position.

l As a lever 29h is turned about its pivot at or near the end of forward movement of actuator bar I3, it moves the bai` 29d laterally a's described in application Serial No. 701,970, so that the shoulders of the notches 29e engage the key-stem locks 29 moving the latter from engagement with the notches 29e of the key stems. The springs 21 associated with the depressed keys return the latter to normal position.

The'bar 29d is returned to normal position by the spring 29j. -On return of the bar 29d the shoulders of the notches 29e move away from the key-stem locks 29. The spring 60 associated with the bar lock of lowest denomination, acts to pivot all the released bar locks so that the slots 48 etc. are moved from registration with the actuator bars and the solid portions of the bar locks are moved into the notches 38 of the actuator bars to lock the, latter in normal position. The individual springs '|72 associated with the released zero locks move the zero locks so that their ends are positioned in the notches 39 in the actuator bars. The key-stein locks again engage the key stem notches 29h as the arms 56, etc., and 16, etc., are moved by the pins on the bar locks and zero locks.

When a number is to be subtracted the subtracting lever 98h is moved to and held in operative position. It is to be understood that latching means of any desired form may be provided for retaining the lever 98h lin operated position if it is not desired to manually hold it in operative position. Lever 98h acts through the links 98d and 98g to move the levers 98.about -their pivots. The levers 98 act through bail |0|d to move the ends I0 lb of the transfer levers from engagement with the pinion cams 9| and out of the paths of movement of the raised portions 9|a thereof to permit subtractive movements of pinions 90 through zero position if required;

The movement of links 98d and 98g by subtracting lever 98h also rocks bell cranks 98pv and the slides 62 are moved upwardly on pinion frames 92 so that the cutout portions 62o move from registration with the frame notches 921 and solid portions of the slides become aligned therewith.

. The studs 62h adjacent the ends of the slides engage the arms 63a of bellcranks 63'and turn the latter to move the latch trips 92j which contact the pins 92g on the latches 92h, moving the latches out-of engagement with thepinion frames 92, so that springs 92 may act to mesh the pinions 90 with toothed portions 85 for operation during the rearward movement of released actuator bars. The frames 92 then are retained out of the position in which the accumulator gears can mesh with the segmental gears by the bars |38.

The ,depression of numeral keys controls the lactuator bars in movement 'as previously described; when theoperating handle is moved forwardly the shaft |03 turns and the cams |36 permit the levers |4| to retract the bars |38.

Some slight movement of the frame 92 in a counterclockwise direction will result on release of the elements above described. Then, as the actuating handle is pulled forward, the main drive shaft |5| will be rotated clockwise and the is, those segmental gears 84 which are permitted to move, can move only from blank to zero position before the accumulator gears 90 engage the segmental gears 84. Due to the fact that the alcance teeth of both the segmental gears 84 and the accumulator gears 90 are large, they will mesh suiiiciently accurately during the rearward movement of frame 92 to prevent any inaccuracy in the position'of the accumulator gears relative to the segmental gears. Thus the teeth on the accumulator gears 90 Will be disposed somewhere between-the proper teeth on the segmental gears 84 and will be correctly positioned when these gears come intofull mesh. Upon continued forward movement of the actuating handle, the parts associated therewith will move to the positions shown in Figure 12 and the actuator bars I3 will move rearwardly a sumcient distance to properly index the segmental gears 84 and the accumulator gears 90.

After the actuator bars havev indexed the printing segments lin printing position, platen '88 is moved against the type faces to effect printing, as previously described. After printing has taken place, studs 88g carried by links 88o move toward the notches 921' inthe pinion frames and since these notches are now closed by the slides 82 the studs g engage the slides 62 on the frames 92;

In the arrangement described, the studs 88g are carried on members 88k to which springs 80u are connected (Figure 9)'. Consequently, -on engagement of studs 88g with slides 62 the springs 8811. are further tensioned by the pins 88p moving with links 88e while studs 88g are temporarily vheld by engagement with slides 62.- On tensioning of the springs 881i, which are stronger than to move the frames to carrythe pinions 92 from toothed portions 95 and` into engagement with pinion locks 95. Studs 88g may be xed to links 88e and act 'directly on the frames but are pref' erably resiliently mounted thereon for a purpose which will hereinafter become apparent. 'As the pinions are demeshed the pins 92h on frames 92 permit the springs 63d to move the latch trips 92j rearwardly against pins 92g on latches 92h, which, however, are held away from frames 92 by the studs |05.

When the operating handle is released and moves rearwardly, the main springs |5|e act to move the restoring frames |04 forwardly. The

studs |05 move away from the latches 92b which are moved by' their springs 92d to engage the pinion frames 92 for holding the pinions 9001113' of engagement with the toothed portions '85 and in engagement with thepinion locks 95. As the links 88e are moved rearwardly the studs 88g move from engagement withl the slides 82 on pinion frames 92,'the arrangement being such that the studs |05 move more rapidly than the studs 88g, so that the latches 92h may maintain the pinions demeshed during the return of the bars I3. The springs 88u act'to maintain the studs- 88g against the slides 62 on the frames 92 as the pins 88p move with links 88o until the latches- As the restoring framesl04 turn with the shaft` |03 they drive theactuator bars forwardly toward normal position'and restore the printing segments to position their blank portions at the printing line, but they do not effect operation of the numeral pinions 90 which are held in disengaged relation by the latches 92h. If, during the prior rearward movement of the actuator bars, any of the numeral pinions 99 had moved from zero through the nine position (subtractively, the pinion' of higher order is operated to effect the transfer by suitable mechanism such as disclosed in my Patent No. 1,938,907.

'I'he cams |36 turn with the restoring frame shaft |83 and release the bars |38 for engagement with the pinion frames 92 at the end of the rearward stroke of the operating handle for further locking the numeral pinions in engagement with the pinionl locks 95. Before the pinion frames are engaged by the bars |38, restoring frames |94 move the actuator bars to restore all of the actuator bars to their normal position.Y The key-stem locks, released bar locks, and zero locks are actuated bythe operation of the cams |3a on the actuator bar or bars, and the bar locks, zero locks and depressed keys are restored to normal position, all as previously described. Y

At the end of the subtracting operation the subtracting lever 9811l is released. When latching means arev provided ,"for this lever, as suggested above, the release of .such latches may be effected automatically lin any desired manner.

.to move the slides 6'2 downwardly moving ythe studs 62h away from the arm 63a of the bell cranks. The bell cranks are restored and the latch members 92;! are againpositioned by springs 63d above the pin 92g on the latches 92h. The'v springs 32d of latches 92h restore the latches with pins 92g in contactv with the ends of trip' members 92j.

When total key 14 is depressed-the shaft"14h is 'turned and acts through links 141 and '14n tc move the slides 62 upwardly. This upward movement of'the slides 62 does notaffect the lever 98h because of the pin and slot connection 62d, 62e. The pins B2b near the end of slides 62 also act on the bell. cranks 63 for operating the latch tripping members '92j to release latches 92h to permit meshing pinions 90 with toothed segments :84 during the rearward movement of the actuator bars.V

' It will be rememberedthat the total key has a lug -Mawhich overlaps a lug' '|5c,on the subtotal key 15, so that depression of the total key also affects depressionof the subtotal key. Co'nsequently, when key 14 is operated the links 15j' and 15h are operated" through shaftV 15e and act on the arms |29b on shaft l|29 to move the cipher locks |34 upwardly so that their upper ends are positioned adjacent thefshoulders |33fz:VA on the actuator bars. After a series of adding or subtracting operations have been performed. some of the numeral pinions 9,0 have moved away from the zero position, either by the entry of amounts through operation ofl keys in corresponding columns or as a result of transfer operations, and have their cams 9| positioned so that the raised .portion 9|b ,of cam 9| is out of engagement with the corresponding cipher lock lever |24. The springs |32 associated with these cipher lock levers turn the levers about the shaft Y.

Y O11 Te'- lease of the subtracting lever 98h it is restoredlatches 92h are operated by springs 92d to en- ||a .to maintain the Vupper end of the levers in contact with the cams 9| and the lower end |26 of each lever acts on the corresponding cipher t l Ihe cipher locks |34 for all denominations to the right of any column in which a numeral has been entered are also swung about the shaft |29 so that their ends are out of the path of the shoulders |33. This is effected by cooperative relation of the. cipher locks to permit the printing of ciphers to the right of a column having a numeral therein, as disclosed in my Patent No. 1,938,907.

The movement of links '|5f and 15h. also causes the studs l to engage the arms of bell' cranks 63 moving the latch tripping members 92j for releasing'the latches from engaging relation with the pinion frames 92' Pins 6217 on slides 62 also perform this function on depression of the total key itself. Although there is`a seeming duplication of function, it may bestated that pins 62h are provided especially for eiecting release of the latches on subtracting operations as previously described.

Depression 'of subtotal key 15 vby Vtotal key 14 also acts throughA studs lc'and 15a on the subtotal key to move the bellcranks 6| and 13a (Figs. 3 and 4), so that all of the bar locks and all of the zero locks are simultaneously released to permit the actuator bars to move in accordance with the amount entered in thenumeral pinions 90. jv

When the operating handle connected to the main shaft is rmovedvforwardly `the restoring frame shaft |03 isfturned and the cams |36 carried therewith to permit they lever 4| to retract the bars |38 from engagement with the pinion frames 92. The pinion frames 92 are thereupon moved by the springs 92a so that the numeral pinions 90 move from engagement with the pintioned in the path of shoulders |33 in orderfto hold the locks rmly in raised position. The

latches |35 cannotv engage the --cc'xrresponding cipher locks |34 which have been moved about shaft |29 by levers |24 since either figures or zeros are to be printed in the corresponding columnS.

A As the frames 92 movethe pins 92h swing the f trips 92j' from engagement with pins'92g andA The actuatorbars |3 for coulmns in which lto normal position by their springs.

numbers have been entered move rearwardly to an extent determined by the number entered in the numeral pinions, the movement of the pinions and the indexing of the printing segments being limited by the 'engagement of the raised portion SIb of cams 9| with the ends |0|b o1' the transfer levers which act as zero stops for the pinions. The actuator bars I3 for columns to the left of the amount on the numeral pinions are held against any movement 'as the related cipher locks |34 have their upper ends positioned in the paths of movement of and are heldirmly against the shoulders |33`on these actuator bars as a result of operation of the total key.

After the amount on the numeral pinions 80 has been transferred to the printing segments 84, the platen 88 is moved through links 88e against the printing segment to eiect printing of the total. After printing hasl taken place in a totalling operation the studs 88g on the links 88e engage the slides 82 and rock the pinion frames forwardly so that the pinions 90 demesh from the toothed segments 85 and engaged the pinion locks 95, as described for subtraction.

When the operating handleon the main shaft is released and moves rearwardly the studs on the restoring frames |04 move away' from the latches 92h, which engage the pinion frames 92 to hold the pinions demeshed during the forward movement of the actuator bars by the restoring frames |04, as in subtraction.

As the restoring frames |04 move the actuator bars I3 to normal position, the racks 31 move the printing segments 84 so that the blank spaces are again presented at the printing line. In the nal movement of the actuator bars, key-stem locks,

bar locks and zero locks are restored to locking relation with the actuator bars, all as previously described. The movement of the bar 29d to release the key-stem locks, bar locks and zero locks also eiects releasing of the key-stem lock 14g for the total key and subtotal key which are restored On restoration of the subtotal key the links 15j and 15h move the cipher locks and members '|51 to normal position.

On restoration of total key 14 the slides 62,

latch trip 92f, etc., are restored to normal position on movement of the links '|51' and 151|.. 'I'he springs |3I, |32 associated with the cipher locks and the cipher lock levers also act to restore the latter to their normal position.

When the subtotal key is depressed to take a subtotal, the operation is as described above, except that slides 62, being connected to the total key but not to the subtotal key, are not moved upwardly and the studs 88g on the links 88e cannot act to demesh the numeral pinions 90 from the toothed portions 85 of the sectors 84 after printing has taken place. Consequently, during the restoring operation `of bars I3, the printing sectors and the pinions are operated by the racks 31, the printing segments being restored to blank position and the numeral pinions being operated to reinsert the amount in the pinions. At 'the end of the rearward -stroke of .the operating handle the bars |38 are driven against the pinion frames 82 by release of the latches |40 and effect demeshing of lthe pinions 90 from the toothed portions 85 of segments 84,' as in addition.

It should be noted that in addition the latches 92a maintain the pinions from operative relation with the actuator bars during their rearward movement and that when printing has been eifected the restoring frame studs. |05 release the latches. In subtracting, totalling andsubtotalling operations the latches are released immediatelyupon operation of the controllever or keys but the pinions do not becomeoperatively engaged with the actuator bars in their rearward stroke until the active printing members areindexed to zero positions because of the control of the pinion frames by the restoring frame shaft acting through bars |38.

The slides 62 carried by the frames are also directly controlled by the subtracting lever and total key to demesh the pinions at the end `of the rearward stroke of the bars so that the forward bar movement does not affect the pinions. Since the subtotal key does not operate the slides 62 the pinions are actuated in both movements of the bars so that the registered value is restored to the pinions.l

It should be understood that many of the parts illustrated are shown in a form chosen purely fo: simplicity of illustration and to provide a complete showing of related parts and do not necessarily represent preferred embodiments. For example, the mechanism for moving the platen frame to eiect printing and for moving it away from the type faces after printing is illustrated only for completeness of description and may be replaced by various well known types of.print ing mechanisms.
